Biotechnology has produce crops that are resistant to certain pests, crops that produce high yields, and more nitrogen-efficient crops. what is a negative impact that bioengineered plants may have on the environment?

a) beneficial insects may be adversely affected.
b) plants have an increased resistance to insect pests.
c) there is an increased need for inorganic fertilizers.
d) genetically engineered plants may have a longer shelf life

A)Beneficial insects may be adversely affected.  

Explanation: Beneficial insects may be adversely affected. While some insects are plant pests, many others a necessary to pollinate the flowers of plants that eventually give us fruits, vegetables, and seeds for human use. Bioengineered plants often require less water, fertilizers, pesticides, and the use of herbicides.

evidence and logical support is essential for a scientist to do in order to maintain credibility. this is because no one can believe without any logic and without any evidence.hence a scientist can maintain credibility by proving himself and by answering logically so experiments prove very beneficial. logical hypothesis give conclusion which is acceptable. therefore, there are two main factors to maintain credibility by a scientist is evidence and logical support.
